EVERYDAY SCIENCE

Detailed explanation-1: -In ecology, the term “niche” describes the role an organism plays in a community. A species’ niche encompasses both the physical and environmental conditions it requires (like temperature or terrain) and the interactions it has with other species (like predation or competition).

Detailed explanation-2: -The role or job of an organism within a community is its niche.

Detailed explanation-3: -When a subpopulation migrates into a new niche (an environmental or social area sectioned off from the rest of the group), that subpopulation will breed amongst itself, emphasizing characteristics that are carried along. This can contribute to speciation.

Detailed explanation-4: -Increasing species diversity can influence ecosystem functions-such as productivity-by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
